Keto Lemon Bars

The lemon bar I’ve been making for the past 3 weeks straight. Tastes unreal.Hey all! It’s been a while since I’ve made a keto recipe so delicious I needed to share it  I had a ton of lemons from my boss’s tree at home and went to town making one of the best and easiest desserts I’ve ever had. I’ve tweaked the original recipe a bit over the 4 batches I’ve made and I have to say it’s so hard to go wrong with these bars. Hope you enjoy!
